MODELS OF INDIVIDUAL LINEAR DIMENSIONS NECESSARY FOR THE CONSTRUCTION OF THE CORRECT FORM OF DENTAL ARCHES IN YOUNG MEN WITH A WIDE FACE, DEPENDING ON THE FEATURES OF ODONTOMETRIC AND CEPHALOMETRIC INDICATORS

Abstract

The aim is development and analysis of regression models of linear dimensions necessary for the construction of the correct form of dental arches in young men with a wide face, depending on the features of odontometric and cephalometric indicators. Material and methods: Primary computed tomographic indices of tooth size and cephalometric parameters of 44 young men with normal occlusion were obtained from the data bank of the National Pirogov Memorial Medical University, Vinnytsya. Face type was determined using the Garson morphological index. In licensed statistical package "Statistica 6,0" developed regression models of linear dimensions necessary for the construction of the correct form of dental arches. Results: As a result of researches, it is established that all 18 reliable models of the sizes used for construction of the correct form of dental arches, depending on peculiarities of odontometric and cephalometric indices with a coefficient from 0.645 to 0.944 are constructed. Built models in adolescents with a broad face type more often include odontometric than cephalometric indicators. The most commonly used odontometric indices are: the width of the crowns of the teeth in the mesio-distal and vestibulo-oral directions, as well as the distance from the middle of the cutting edge to the apex of the root of the teeth in the vestibulo-oral direction. Conclusions: In adolescents with a broad type of face with normal occlusion, all 18 possible reliable regression models of reproduction of the individual characteristics of the dental arches of the upper and lower jaws were determined and analyzed.
